Question about period

Melissa • Hello my name is Melissa Bell and I was diagnosed with stage two endo this past august.
I was just wondering I finally started bleeding on mon night after 22 days. It came real heavy and then four hours later it spotted. I spotted the next day and then nothing after that. Now I am all normal yellow urine. So really only bled for one day. I am having my estrogen levels checked to see if that's the problem.
